My CCRM IVF Journey

Our successful journey through IVF #2 at one of the world's top fertility clinics

Trisomy 2

Posted by auntiem10 on October 25, 2010

The genetic counselor at CCRM recently told us that our lone abnormal blast (Embryo #3) had Trisomy 2. An extra copy of the second chromosome was found during PCR testing.

Chromosome #2 is the second-largest chromosome in the genetic code and contains 8% of the entire DNA in cells. The CCRM genetic counselor said that this embryo would likely never have survived implantation. Trisomy 2 mosaicism appears to be the outcome if the embryo does implant, and I wouldn’t recommend researching it. You will see some pretty terrible results and images.

This embryo was graded as a 6AB, one of the highest-rated blasts. I’m guessing it would have been chosen third in line for transfer, behind our 5AA and 6AA. I am very thankful we elected to add CCS testing!

    Me too! I am quite certain that my hopeful pg will be more relaxed due to CCS. It was expensive but it bought us peace of mind.

    That’s amazing a trisomy 2 even made it to blast at all. So glad it was caught and weeded out!

    We also learned that our highest graded blasts were abnormal. This was interesting to us and made us wonder if that explained our IVF failures. Hoping that those two embryos make themselves nice and comfortable for 9 months! 🙂

  4. I am glad we did the CCS testing as well. My excellent blast of 5AA turned out to be abnormal and it would have been first in line for a transfer. I don’t know why it was abnormal. Hmm… now this post makes me want to find out!

    Me too, so thankful for CCS. So very glad we chose to do it. It does give a lot of comfort knowing our embryos were most likely normal.
